Old battery 12.65 v. New battery 12.88v. Is the old battery good?
Check the fuses, mines was the 175 amp was blown
Where's the fuse located?

Can a bad auxiliary battery cause the car to not start?
Is this why the remote start might not work?
Yes also a check engine would cause remote start to not work
In my 2015 Chevy Impala the remote start won't work at all if there's a code making the check engine light come on. My 2010 Impala would still start with the remote start, but once it detected a fault via throwing a code it would cancel the remote start and shut down the engine.
@@dylantroutman6575I have the same problem with mi Impala 2015 ¿What did you do to solve it?
My car radio is turning off & on but both batteries are good
Any fix having same issue
Mines is doing the same
@@casperhayden8286yes I figured it out. The 175 amp fuse for my Malibu was blown and needed to be replaced.
My 2015 chevy malibu has no power at all what can cause that
It may be in Limp Mode, which will need a scan for error codes to know why.
My two and I already the code I was getting I changed map sensor and Evap canister and I still get the same code know I got this code p305F but i haven’t got no issues it star up right away it just a limp mode while driving
